USB Drive problems

Don't really know where to post this thread to be honest so thought I would put it here..

I have a USB drive and it has a partition which is write protected. I just need to format the whole drive so it can be used for other things. There is no write protect switch on it or anything like that. I've tried doing the whole Computer Management route but it gives me the same problem and I have also tried formatting it in DOS. Does anyone have any other ideas on how to format this drive?

done the show hidden files and they are also locked... its something to do with the way they were put on the USB drive.. It was for a congress done in 2009 and it was supplied with the details on the USB disk. I've had to talk to the manufacturer to find out how to break it. :lol:
